Introduction

oadRunner from MUSICAM USA contains the latest in
technologies to bring you the best possible combination of

features and performance available from any portable codec.
Inside its rugged but lightweight enclosure, the RoadRunner contains a
full-featured monaural audio mixer with two microphone inputs and a
third input switchable between microphone and line levels. The analog
audio section also contains a wide array of outputs: two individually
adjustable headphone outputs, plus two unbalanced and one balanced
line level output.

RoadRunner’s digital section contains the widest selection of
compression algorithms available in any portable codec. RoadRunner’s
premier coding algorithm is MUSICAM, MUSICAM USA’s fully
compatible enhancement to the ISO/MPEG Layer II encoding standard.
Industry standard ISO/MPEG Layer III as well as G.722 are also
included. RoadRunner can send and receive up to 20 kHz monaural
audio transparently over digital transmission systems and is compatible
with more codecs than any other similar device. RoadRunner can send
the same audio program to two locations simultaneously. RoadRunner
also contains ample memory to support upgrades to its algorithm suite
and operating system as developments and improvements occur. You
can even make software upgrades in the field, without having to return
the RoadRunner to the factory.

RoadRunner also contains powerful ancillary data features that enable
bi-directional RS232 ancillary data, up to 4 relay contact closures and
far-end remote control when connecting to another compatible codec.
These ancillary data features are available with all algorithms except
G.722. In addition, the powerful Logic Language offers a large selection
of automated functionality programming that is unavailable from any
other manufacturer.

RoadRunner offers more connection options than any other portable
codec. With a plug-in ISDN terminal adapter (RoadRunner’s standard

11

RoadRunner USERS GUIDE

configuration), RoadRunner can connect directly to another ISDN codec
at bit rates from 56 to 128 kb/s. RoadRunner also accepts any of the
digital interface modules available from MUSICAM USA, and can be
used over any digital facility that accepts V.35, X.21 or RS422 interfaces,
in addition to ISDN.

RoadRunner’s built-in auto-dialer can be used to make all connections
when using any one of MUSICAM USA’s available ISDN terminal
adapters. RoadRunner’s speed dial directory holds up to 256 entries.
Each entry not only holds the numbers to dial, but also all configuration
and connection information, making the RoadRunner easy to use with
any connection type.

Key Features

oadRunner is a complete package. It is housed in a rugged case

and includes a foldaway handle. The complete RoadRunner

package weighs less than 9.5 pounds (4.3 kg). Inside the
RoadRunner case is a full featured 3-channel monaural audio mixer, an
18-bit A-to-D converter, a multi-algorithm codec, a slot for available
plug-in digital interface device (an ISDN terminal adapter is supplied
as standard), an auto-dialer, international AC and DC power supplies,
and a powerful command processor. If you choose, you can connect
your RoadRunner to any digital transmission system through available
ISDN, X.21, V.35 or RS422 digital interface modules.

RoadRunner uses state-of-the-art compression technologies to provide
bi-directional broadcast quality monaural audio over a single 56 or 64
kb/s line. In addition, the RoadRunner can provide bi-directional 20
kHz monaural audio transparently over a single ISDN line at 112 or 128
kb/s. Ancillary data is supported at all bit rates with any MPEG
algorithm.

RoadRunner is easy to use. The RoadRunner front panel controls have
been kept to a minimum, are simple to use, and are clearly labeled. The
front panel controls include mixing levels for three inputs (two
microphone and one switchable mic/line) and individual local and
return level adjustments for two separate headphone outputs.

All audio connections are made through industry standard connectors,
logically located on the front and rear panels. Two balanced XLR
microphone inputs are located on the front panel, as are two standard
¼” headphone jacks. An additional balanced input, switchable
between microphone and line levels, is located on the rear panel. Also
on the rear panel is an XLR balanced line level output and two ¼”
unbalanced local and return audio outputs, ideal for PA feeds,
recording, etc.

RoadRunner USERS GUIDE

The RoadRunner can be equipped with any of the Digital Interface
Modules available from MUSICAM USA. Available modules include
internal Terminal Adapters (with or without built-in NT-1), V.35, X.21,
RS530 or RS422.

Front panel indicators include Power, On line, Norm (signal level) and
Clip (over level). There are also four Cue LEDs indicating the state of
the internal relays. The front panel keypad can be used to access all
functions of the RoadRunner and built in Terminal Adapter, and is also
used as the dial keypad. A backlit display with adjustable contrast
provides menu, maintenance and dialing displays.

Since RoadRunner features and audio quality are implemented in
software, rather than hardware, the RoadRunner can be upgraded in
the field should improvements become available. Software can be
downloaded directly from our Web Site (www.musicamusa.com) or we
can send you an upgrade kit. This prevents your RoadRunner from
becoming obsolete.

CODEC Compression Algorithms

There are currently three coding algorithms used in the RoadRunner.
Each has its advantages and disadvantages. Which algorithm you use
depends on a number of factors, including desired audio quality, delay
and compatibility with other codecs.

ISO/MPEG Layer III

ISO/MPEG Layer III can provide full duplex, 15 kHz monaural audio
using only one 56 or 64 kb/s ISDN ‘B’ channel. When using 112 or 128
kb/s, transparent 20 kHz monaural audio is possible. The inherent
drawbacks of this algorithm are the long coding delay times and poor
cascading characteristics. In addition, post processing may highlight
some artifacts.

MUSICAM and ISO/MPEG Layer II

The premier coding algorithm used in RoadRunner is MUSICAM,
MUSICAM USA’s encoding enhancement to the ISO MPEG Layer II
algorithm. MUSICAM encoding is fully compatible with all MPEG
Layer II decoders, and since the enhancements area part of the encoder,
any Layer II decoder will sound better when connected to a

4

RoadRunner USERS GUIDE

RoadRunner. MUSICAM can deliver full duplex, 10.5 kHz monaural

audio on one ISDN ‘B’ channel. When using 112 or 128 kb/s,
transparent 20 kHz monaural audio is possible. Although a narrower
bandwidth at 56 and 64 kb/s than MPEG Layer III, audible advantages
are higher transparency, lower delay, less noticeable artifacts and better
results when cascading. At 112 and 128 kb/s, MUSICAM offers
transparent monaural audio and better cascading than either standard
ISO/MPEG Layer II or Layer III.

G.722

G.722 is one of the earliest audio coding algorithms to be standardized.
G.722 is a relatively simple algorithm based on ADPCM (Adaptive
Predictive Pulse Code Modulation) offering full duplex, 7.5 kHz audio
over a single ‘B’ channel. The essential advantages of G.722 are its
compatibility with most other codecs and very low delay times. The
main disadvantages are its limited audio fidelity, poor signal-to-noise
ratio and poor cascading.

Broadcast Capabilities

The RoadRunner can be configured to send the same audio program to
two different locations simultaneously. In addition, the RoadRunner’s
decoder can receive the return audio from both locations, and you can
easily switch to monitor the return audio from either location.

You can use any supported algorithm, and can even use different
algorithms for the send and return audio. For example, a typical
application involves sending high quality Layer III audio to the studio
from the remote location, but low delay G.722 can be used for the return
audio.

Ancillary Data

A bi-directional RS232 data path is provided for end-to-end ancillary data
communications when using any MPEG algorithm. Baud rates up to
38,400 are supported.

Unpacking and Installing

our RoadRunner comes with an AC line cord and an RJ-45
jumper cable if an ISDN terminal adapter is installed. An

appropriate interface cable, available from MUSICAM USA, may
be required if a non-TA module is installed. An optional carrying case
is available.

Unpack your RoadRunner and plug it in to an appropriate power
source. Please note that the RoadRunner has “World” AC and DC
power supplies, and can be used anywhere without changing voltage
settings. RoadRunner can operate in any position, and may be stacked
or shelf mounted if desired. However, note that RoadRunner is fan
cooled, and the rear mounted fan should not be blocked.

Your RoadRunner is shipped to you in Loopback Mode. When in this
mode, you can test all audio input and output connections. When your
RoadRunner is in the loopback mode, and all audio connections have
been made properly, you should hear any audio input to the
RoadRunner at the output of the RoadRunner. Please remember that
for normal operation, the RoadRunner must not be in loopback mode.

RoadRunner Connections

RoadRunner‘s connection to the digital transmission medium is made

through a Digital Interface Module (DIF). The RoadRunner supports
one digital interface module that plugs into a slot in the rear panel.
Two types of DIFs are available, Terminal Adapter (TA) and non-TA.
TAs connect directly to your ISDN line and allow dialing directly from
the RoadRunner keypad. Non-TA type modules can connect to
external terminal adapters or most other digital facilities, such as
dedicated lines, fractional T1 or satellite systems through appropriate
interfaces.

6

RoadRunner USERS GUIDE

MUSICAM USA offers three different TA modules, the TA101, TA201
and TA301. The TA101 and TA201 both provide an ‘S/T’ interface and
require an external network interface device (NT-1) for use in North
America. Elsewhere, the NT-1 is provided by the phone company, and
an external NT-1 is not required. The TA301 provides a ‘U’ interface
through its built-in NT-1 and therefore can be used only in North
America.

Connect the ISDN line to your internal terminal adapter (if so
equipped). Be sure that there are no alarm conditions present on the
terminal adapters or the NT-1. There should be no flashing LEDs or
other alarm indications for proper operation. The TA201 and TA301
terminal adapters have sanity LEDs that can be observed from the back
of the RoadRunner. The green LED must be solid ON for proper
operation. If using an external NT-1 with your terminal adapter, the
‘U’ interface (the wall connector) requires a 2-conductor cable. The
‘S/T’ interface (the RoadRunner side) requires an 6-conductor cable.

Two non-TA digital interfaces are also available for the RoadRunner.
The DIF101 interface is used for connecting transmission systems using
X.21, RS422, RS449 or RS530 interfaces. The DIF102 interface connects
to transmission systems using the V.35 protocol.

All audio inputs and outputs are through industry standard connectors
located on the front and rear panels. Two balanced XLR microphone
inputs are located on the front panel as are two standard ¼” headphone
jacks. An additional balanced input, switchable between microphone
and line levels, is located on the rear panel. Also on the rear panel is an
XLR balanced line level output for received audio from the far end unit
and two ¼” unbalanced local and return audio outputs to feed
recorders, PA systems, etc.

The four relay outputs and optically isolated inputs are accessed
through the DB-25 connector, and there is a DB-9 connector for
ancillary data, remote control and software upgrades. Connectors for
AC power (100-240 VAC, 50/60 Hz) and 12 VDC power are also located
on the rear panel, as is the power switch.

You can connect a professional quality low impedance microphone
directly to either XLR microphone input on the front panel. A
microphone can also be connected to the mic/line input on the rear
panel, setting the level switch accordingly. High impedance
microphones, or microphones with other than XLR connectors must use
an external matching transformer or adapter. Phantom power is not
provided. Balanced monaural line level audio is input through the XLR

RoadRunner USERS GUIDE

Input 3 connector on the rear panel, setting the input level switch
accordingly.

Mic/Line mixing is accomplished using the three input level controls
located on the front panel. When audio is present, adjust the levels so
that the green ‘NORM’ indicator illuminates and the red ‘CLIP’
indicator does not. It is recommended that the input level be turned
down if an input is not connected.

Two sets of headphones with ¼” jacks can be used without adapters.
When stereo headphones are used, the output will be monaural, to both
ears. Do not use monaural headphones with 2-conductor plugs. The
audio source to the headphones, local or return audio, is adjusted using
the two monitor level controls located above each headphone output.
Level adjustments for each headphone are independent.

Balanced Line level return audio (audio from the far-end) is available
through an XLR connector, and unbalanced line level local and return
audio is available through two ¼” phone jacks. All output levels are
fixed at 0 dBu relative to input levels (no insertion gain/loss).

A 9-pin connector for RS232 ancillary data, remote control and software
maintenance is included, as is a 25-pin connector for the four optically
isolated inputs and relay outputs. In addition, one slot can hold any of
the plug-in digital interface modules available from MUSICAM USA.
Available modules include ISDN Terminal Adapters, RS422, X.21, and
V.35 interfaces. Although primarily an ISDN device, you can also use
the RoadRunner with other digital transmission systems, such as
Switched-56, dedicated lines, fractional T-1 and satellite systems using
the appropriate digital interface module.

The RoadRunner can be used with 12 VDC or AC power. The universal
AC power supply needs no jumpers, and works with 94 - 250 VAC, 50
or 60 Hz. Power consumption is approximately 40 Watts. Please note
that the RoadRunner does require forced-air cooling, and that the rear
mounted cooling fan should not be blocked.

The RoadRunner has a rich set of remote control commands that allow
you to control it from an attached terminal or computer. A separate
RoadRunner Remote Control Manual is available from MUSICAM USA
upon request.

Installing the Digital Interface Module

A digital interface module is required to use your RoadRunner with a
transmission system. Only one DIF module can be installed in the
RoadRunner at a time. If you are using a DIF101 or DIF102 module for
RS422, X.21 or V.35 interfaces use the appropriate cables, available from
MUSICAM USA.

All DIFs are installed in the slot in the rear of the RoadRunner. You
should make certain that the module is installed correctly, not forced
and has been securely fastened using the provided screws. You should
not attempt to operate the RoadRunner if the DIF has not been properly
installed and secured.

Once installed, the DIF module and interface type must be selected on
the RoadRunner menu for proper operation:

<Maint><Dig I/F><Type>

RoadRunner USERS GUIDE

RS422/RS449/RS530 and X.21 Using the DIF101 Digital
Interface

The RS422 interface specification defines only the electrical voltages at
the interface and leaves the pin-out and meaning of the pins to the
hardware designer. The RS449 interface specification utilizes the
electrical specifications of RS422 but specifies a mechanical connector.
RS449 equipment is therefore electrically compatible with the
RoadRunner RS422 interface when an appropriate adapter cable is
used. RS449 also specifies numerous control signals besides clock and
data, which are not used by the RoadRunner. The RoadRunner RS422
interface pin-out is specified in Appendix A.

The RS422 interface also has a separate clock for the transmitted and
received data. The RS422 interface can also echo the transmitter clock.
If the terminal equipment clocks the encoder data with the echoed
clock, the RoadRunner may be located up to 4000 feet (1219 meters)
from the terminal equipment without concern for encoder-to-clock
skew.

The X.21 (also known as RS530) interface specification is, in general, a
very complex specification. The general specification allows a
mechanism for communication between the customer equipment and
the network. This communication path can be used for things such as
dialing. A sub-set of the specification, called the leased circuit, used
here, restricts the interconnection to only clock and data and a very
simple control signal. The mechanical connector required is the DB15
with the pin-out specified in Appendix A. The electrical specification
for X.21 is identical to those of RS422. The X.21 interface has only one
clock for both transmit and receive signals.

Since the X.21 uses the RS422 electrical interface, the RoadRunner can
use the same connector for both interfaces. In the case of the X.21
interface, the single clock is used internally for both transmit and
receive timing. To change the hardware configuration of the DIF101
interface card between X.21 and RS422/RS449, change the position of
jumper J4 on the interface module. The jumper on positions 1 and 2
sets X.21 operation, and when on positions 2 and 3, the card is set for
RS422/RS449 operation.

Once the DIF101 module is installed, select the appropriate interface
type from the RoadRunner menu:

12

RoadRunner USERS GUIDE

<Maint><Dig I/F><Type><type>

where type can be either X.21, X.21XTA or RS422.
Select RS422 when connecting the RoadRunner to any RS422 network

interface. When connecting to any X.21, RS449 or RS530 interface, select
X.21XTA if the external network interface device recognizes a change­of-state of the DTR/CON line. This enables the RoadRunner to
terminate the connection when you press the END button. Otherwise,
select X.21 as the interface type.

V.35 Using the DIF102 Digital Interface

Each interface defines a voltage level for each of the signals. In the case
of V.35 and X.21, a connector type is defined as well. The large,
rectangular block connector defined in the V.35 specification is not used
by the RoadRunner because of its size. Instead, a smaller DB15
connector is used. In the case of the V.35 interface, the RoadRunner
conforms to the electrical specification but requires an adapter cable to
convert the DB15 connector to the connector specified in the V.35
specification. The connector and the pin-out chosen for the V.35
interface in the RoadRunner are a common deviant found in many
systems. An adapter cable is available from MUSICAM USA or
distributors, or can be made following the diagram found in Appendix
B. It is important to remember that V.35 has a separate clock for
transmitted and received data.

Once the DIF102 module is installed, select the appropriate interface
type from the RoadRunner menu:

<Maint><Dig I/F><Type><type>

where type can be either V.35 or V.35XTA.
When connecting to any V.35 interface, select V.35XTA if the external

network interface device recognizes a change-of-state of the DTR/CON
line. This enables the RoadRunner to terminate the connection when
you press the END button. Otherwise, select V.35 as the interface type.

ISDN Using the TA101 Terminal Adapter

The TA101 Terminal Adapter plugs directly into the RoadRunner and
provides an ‘S/T’ interface to ISDN. The S/T interface requires an NT-

1, which must be provided by the user for North American operation.
Elsewhere, the service provider supplies the NT-1.

Since every country requires slightly different ISDN control and
signaling information, the TA101 TA requires different ROM chips for
different countries. If you have specified the country in which you will
be using the RoadRunner when ordering, your TA101 will have the
correct ROM chip installed. Please check with your local distributor,
CCS Europe or MUSICAM USA if you will be taking your RoadRunner
to foreign countries. Configuring the TA101 is discussed in later
sections.

Elsewhere, the service provider supplies the NT-1.

The TA201 is pre-programmed with the ISDN configurations for all
countries, and can be used everywhere without the need for changing
ROM chips. Country selection is made in from the RoadRunner’s
menu, and will be discussed later.

and right) arrow keys, the display can be scrolled to show all possible
options and selections.

The alphanumeric portion of the keypad is used for entering
information and for dialing. Each of the 12 keys associated with the
alphanumeric portion of the keypad represent up to four different
characters. Multiple presses of the same key select different characters.

Please note: the QZ1 key is also the space key. Spaces are not entered

using multiple presses of the right-arrow key.

To use the keypad and display, press
the arrow keys to move the cursor
(the [ ] brackets) to the desired menu

selection. Press the ENTER key to
execute the selection or move
down to the next menu level.
Pressing the ⇑ (up arrow) at
any time brings you up one menu
level. At any given time, only a
limited number of selections may
be visible on the display. By
using the ⇐ and ⇒ (left

The left and right arrow keys are used in conjunction with the
alphanumeric keys to move the cursor to the desired position. After the
desired character string has been formed, pressing the ENTER key
executes or enters the string.

In the discussions that follow, the printed sequence
<X><Y><Z> will be used as shorthand to mean: Use the
arrow keys to move the cursor to ‘X’ and press ENTER, then
use the arrow keys to scroll to ‘Y’ and press ENTER, finally,
scroll to ‘Z’ and press ENTER .

The keys under the ‘DIAL’ label are used to enter and execute dialing
functions such as direct dialing, speed dialing, directory maintenance
and call termination. The last column of keys are ‘Hot’ keys. Pressing
any one of these keys will execute one of the pre-programmed or user

programmed one-button functions. These four keys can also be set up
to close relay contacts on a far-end codec or to execute any remote
control or Logic Language command.

Selecting A Digital Interface Module (DIF)

If the DIF was not factory installed, or if you change DIFs, you need to
select the Digital Interface the first time you use the RoadRunner with
that DIF.

Once a DIF has been physically installed, you must set the RoadRunner
to recognize the module. From the keypad, use the sequence:

<Maint><Dig I/F><Type><Type>

and scroll through the menu to select the installed interface. The choices
are:

TA101, TA201, TA301, X.21, X.21XTA, V.35, V.35XTA and RS422.

!note:

Select the appropriate interface and press ENTER. You can also use the
remote control command CIF from a terminal or computer. Select
V.35XTA or X.21XTA only if your external TA is capable of recognizing
DTR or CON signals for call termination. This allows you to terminate
a connection from the front panel of the RoadRunner. You can also
toggle the sense of the DTR line using the

<DIFx01><DTR/CON>

sequence. If your external TA cannot recognize these signals, then
select V.35 or X.21.

TA Configuration

It is necessary to configure a Terminal Adapter each time you connect
your RoadRunner to a different ISDN circuit.

Three different TAs are available for use in the RoadRunner. All must
be configured properly for use with ISDN, and all require the user to
have certain information, supplied by the ISDN service provider. The
following information must be known before configuring any TA for
use:

North America:

—Switch Type (National ISDN-1 or Custom)

18

RoadRunner USERS GUIDE

elsewhere.

—Switch software version if switch type is Custom
—Switch manufacturer if type is National (for TA101
only)
—SPID numbers for each ISDN ‘B’ channel

Elsewhere:

—Switch type (if required)
—ETSI version
—Sub address (if required)

For TA201 and TA301 configuration for North America,
skip to page 23, skip to page 24 for TA201 configuration

Terminal Adapter TA101 Configuration

The TA101 ISDN Terminal Adapter is no longer available in North
America. Your RoadRunner does support, and will operate with a
TA101 terminal adapter.

!note:

The TA101 terminal adapter provides one ‘S/T’ interface for one ISDN
BRI (2 x 64 kb/s) line. In North America, the Telco provides a ‘U’
interface; therefore, an external NT-1 must be used between the
RoadRunner and the wall jack. Elsewhere, the Telco provides an ‘S/T’
interface and an external NT-1 is not needed.

The TA101 requires country specific ROM chips for use in different
countries. Please contact MUSICAM USA, CCS-Europe or your local
distributor for information if you plan to take your RoadRunner to a
different country.

Probably the most confusing aspect of ISDN codecs is configuring the
Terminal Adapter for the ISDN in your area. This is especially true in
North America, where there are several local ‘flavors’ of ISDN that are
all provisioned differently. Elsewhere, configuration of the terminal
adapter may be as simple as insuring the proper ROM chip is installed
for the country where the RoadRunner is being used.

In North America, the ISDN service provider must supply certain
information to correctly configure the TA101 Terminal adapter:

19

!note:

RoadRunner USERS GUIDE

• Switch Manufacturer, e.g. AT&T, Seimens, Northern
Telecom.

• ISDN ‘flavor,’ e.g., National ISDN or Custom Point-to-Point.

Please note that the TA101 terminal adapter will not work
with AT&T Custom Point-to-Multipoint nor will it work
with AT&T National ISDN software revision 5E9.1.

• Service Provider Identification Numbers (SPID numbers).
National ISDN always requires SPID numbers, some locations
using Custom Point-to-Point may not require SPID numbers.
If SPID numbers are required, most areas use two, but some
implementations require only one (are you confused yet?)

Switch Type (North America and Germany Only)

It is necessary to tell the TA101 what type of switch protocol is being
used at the Telco central office. The ISDN service provider will give
this information to you. You only need to set the switch type once for
each TA since the switch governs both. Use the menu branch:

5E6 and 5E8
switch types are
used only for
Custom Point-to­point ISDN. Use
NTI for Northern
Telecom switch
and NI-1 for all
other National
ISDN

!note:

<TA101><Setup><Sw Type>

then select the appropriate switch type. The CSW command is used for
setting the switch type from a terminal.

In North America, four switch types are available:

• 5E6 is used for AT&T Custom Point-to-Point ISDN version 5E6 or
earlier. This selection is not used for AT&T National ISDN,
regardless of version number.

• 5E8 is used for AT&T Custom Point-to Point ISDN version 5E8 or
later. This selection is not used for AT&T National ISDN, regardless
of version number.

• NTI is used when the switch is a Northern Telecom DMS-100 switch

• NI1 is used for all other National-ISDN-1 implementations,

including AT&T.

German users have three choices: DSS1, 1TR6 and AUTO (AUTO will
not work if a PBX is used). Contact CCS-Europe for information on
which to use in your area.

Special Notes for Switch Type 5E6, 5E8 and AT&T 5E9.1 (North
America Only).

Point-to-Multipoint is not supported.

RoadRunner USERS GUIDE

If your service provider tells you that the switch type is an AT&T
5ESS Custom Point-to Point with software version 6 or earlier,
you cannot enter a SPID and ID number since these are not
supported. Since SPID and ID numbers are not entered, you
must tell the RoadRunner not to look for them, by setting Local
Check to NONE, using the menu sequence

<TA101><Setup><Lcl Chk><None>

or the CLC command.
If your service provider says your 5ESS switch is running

software version 5E9.1 in Custom Point-to-Point configuration,
they may give you SPID numbers. On the RoadRunner, select
switch type 5E8, do not enter the SPID numbers, but enter the ID
numbers and local check values. A TA reset may or may not
result in a “SP1 BAD SP2 BAD” message. When dialing, ‘1 +

area code’ dialing is required, even for local calls.

!note:

If your service provider says your 5ESS switch is running
software version 5E9.1 in National ISDN configuration, you must
contact MUSICAM USA technical support.

Service Provider ID (SPID) Number (North America Only)

For most areas in North American, the TA must be told the SPID
number of the calling ISDN line; that is, the line connected to the
RoadRunner. The ISDN service provider in your area provides this
number. It is important to remember that every time the RoadRunner

is moved, or whenever there is a change in the ISDN line, or even
area code changes, the SPID and ID number, switch type and
possibly other parameters for the TA setup must be updated. You

can store up to 20 ISDN SPID and location configurations for later
recall.

To set the SPID number using the keypad, go down the branch

<TA101><Setup><SPID>

select the ‘B’ channel number, 1 or 2, and enter the provided SPID
number. Please note that each TA supports 2 basic rate ISDN ‘B’
channels, so if your service provider gave you two SPID numbers, you
must enter both of them, one for each ‘B’ channel. Use the CSI
command to set the SPID number from a terminal.

21

RoadRunner USERS GUIDE

Identification (ID) Number (North America Only)

If you are required to use two SPID numbers, then you must use ID
numbers. For the TA101 terminal adapter, the ID number is just the last
four digits of the seven digit ISDN line number connected to the
RoadRunner. Use the

<TA101><Setup><ID>

branch, and enter the ID for each ‘B’ channel. You can use the CLD
command from a terminal.

Multiple Subscriber Number (MSN/LDN — Europe Only)

If you have selected the DSS1 switch type in Germany, then MSNs must
also be used. Use the

<TA101><Setup><ID>

or use the CLD command.

Local Check (North America Only)

If you are required to use ID numbers, you must also set the Local
Check values. Local check tells the TA101 which internal buffers to
check for the ID number. To set this parameter, branch down

<TA101><Setup><Lcl Chk>

and select the ‘B’ channel, then enter the number of the buffer that
contains the ID number. You can use the CLC command from the
terminal. The Local Check values for ‘B’ channel 1 must be ‘T5’ and for
‘B’ channel 2 must be ‘T6’. If IDs are not used, local Check must be set

LLC State

In some areas of the United Kingdom, it may be necessary to toggle the
state of the Low Level Command mode. Use the LLC command sequence

<TA101><Setup>< LLC>

or the CLL command for this if you are having connection problems. In
most other locations, including North America, leave the LLC state ON.

Sub Address, EAZ (Germany) And Interface Mode

The sub-address for an S/T interface TA (TA101) is set by the CSA
command:

<TA101><Setup><Sub addr>

22

!note:

RoadRunner USERS GUIDE

This command is used when a RoadRunner is connected to a digital
PBX. If the TA101 is directly connected to an NT1, then the sub-address
should be set to 0. Subaddresses are generally not used in North
America. In Germany, when using the 1TR6 switch type, subadresses
are required. Use the CSA command to set the EAZ sub address.

The CTF command,

<TA101><Setup><I/F>

sets the interface mode of the internal TA101. For North American
operation with the TA101, the mode should always be set to
IGNORE. For operation elsewhere, initially start with the mode set to

IGNORE. If you have problems making or receiving calls, then set the
mode to ACTIVE.

Reset

After the above parameters have been set, it is necessary to reset the
TA101 Terminal Adapter. The CTR command,

<TA101><Setup><Reset>

is used to reset the internal terminal adapter and to check if the SPID
and ID numbers have been entered correctly for North American
operation. The reset process takes from 20 to 40 seconds to complete,
and the response will be flash for 2 seconds on the top line of the LCD
display. The following responses are possible:

• SP1 OK SP2 OK

• SP1 OK SP 2 BAD

• SP1 BAD SP2 OK

• SP1 BAD SP2 BAD

If you require two SPID numbers, and if you get any response other
than the first, your TA101 has not been configured properly and you
will not be able to make or receive calls. If only one, or no SPID
numbers are required, than any response may be OK. Try dialing and
see if you can connect to another codec. If you get a bad response, or
you cannot dial, please refer to the Troubleshooting Section before
calling for assistance.
